Description

Technical Field

[0001] The utility model belongs to the technical field of biological fermentation extraction, and particularly relates to a defoaming biological fermentation tank. Background Art

[0002] Bio-fermentation tanks are traditional Chinese medicine equipment used in biotechnology and industrial production, usually for cultivating microorganisms or cell cultures. During the fermentation process, the decomposition of microorganisms will produce bubbles (usually carbon dioxide). If too many bubbles are produced during the fermentation process, it will cause quality problems in the product.

[0003] In order to solve the problem of bubbles, most of them are removed by chemical defoaming (defoaming agent) or mechanical defoaming (defoamer) during the fermentation process. The centrifugal force generated by the defoamer is used to eliminate the bubbles. However, most of the existing defoamers have complex structures and require regular maintenance and cleaning, which increases the operating cost and workload, and is not suitable for large-scale promotion in small and medium-sized enterprises.

[0004] In view of this, how to solve the defects in the above technical solutions has become one of the problems to be solved urgently in the field of biological fermentation extraction technology. Utility Model Content

[0057] As Figures 1 to 5 shown, this embodiment provides a defoaming bioreactor 100, which includes a tank body 10 and a defoaming component disposed in the tank body 10 and driven by a drive system 40. The defoaming component includes a rotating shaft 502; the drive system 40 includes a motor 401, and a gear transmission 402 is installed at the driving end of the motor 401. The driven gear shaft of the gear transmission 402 passes through the tank body 10 and is connected to the rotating shaft 502 through a bearing assembly; the drive system 40 is used to drive the rotating shaft 502 to rotate.

[0058] The defoaming component further includes a defoamer 501, and the defoamer 501 is fixedly installed on the rotating shaft 502 by a fixed connection method such as fastening screws.

[0059] In this embodiment, by starting the drive system 40, the drive system 40 drives the gear transmission 402 to rotate. Then, the gear transmission 402 drives the rotating shaft 502 to rotate. Subsequently, the rotation of the rotating shaft 502 drives the defoamer 501 to rotate, generating a certain centrifugal force, and using the centrifugal force to drive the liquid in the tank body 10 to break the bubbles in the tank body 10.

[0060] To solve the problem that most bubbles are removed by chemical defoaming (defoamer) or mechanical defoaming (defoamer) during the fermentation process. Most use the centrifugal force generated by the defoamer to eliminate bubbles. However, most of the existing defoamers have complex structures and require regular maintenance and cleaning, increasing the operating cost and workload, and are not suitable for large-scale promotion in small and medium-sized enterprises. To solve the above technical problems, please refer to Figure 2 As shown, the defoamer 501 includes two groups of connecting plates 5011, which are respectively installed on the rotating shaft 502. The connecting plates 5011 are provided with edges and corners. A bubble-cutting plate 5012 is welded on the connecting plates 5011, and two adjacent groups of the bubble-cutting plates 5012 are arranged in the opposite direction. An inclination angle B is provided between the bubble-cutting plate 5012 and the connecting plate 5011, and B is from 15° to 135°.

[0061] In this embodiment, when the inclination angle B is 15°, the driving force and shear force of the bubble-cutting plate on the liquid are increased, which is more convenient for the bubble-cutting plate to pass through the bubbles and break the bubbles, greatly improving the efficiency of removing bubbles.

[0062] During the fermentation process, even if the defoamer can cut and push most bubbles to the liquid surface, there are still some light small bubbles that cannot be removed and float to the upper part inside the tank body. To solve the above problem, please refer to Figure 2 As shown, a screen 503 is installed inside the tank body 10 far from the drive system 40 by means of fixed connection such as fastening screws, and the rotating shaft 502 passes through the screen 503 and is fixedly installed at the top end of the inner wall of the tank body 10.

[0063] Furthermore, a mounting member 504 is fixedly installed on the rotating shaft close to the screen 503, and at least one group of scraping plates 505 is provided on the mounting member 504 close to the screen 503, and the other end of the scraping plate 505 abuts against the screen.

[0064] In this embodiment, some light small bubbles that are not removed float above the screen inside the tank body. When the drive system drives the defoamer to rotate, it also drives the mounting member 504 to rotate. The rotation of the mounting member 504 drives the scraping plate to eliminate the bubbles floating on the screen.

[0065] In the actual application process, in order to further improve the removal of bubbles, please refer to Figure 1and Figure 4 As shown in Figure 4 , the spraying system 20 includes a delivery pipe 201, and the inlet end of the delivery pipe 201 is used to communicate with an external liquid delivery device. At least one set of connecting pipes 203 is connected to the delivery pipe 201. A control valve 202 is provided on the connecting pipe 203. The other end of the connecting pipe 203 passes through the tank body 10 and is connected to a connector 205. The connector 205 is preferably a tee, and a water spraying pipe 207 and a first spraying ball 205 are respectively connected through the connector 205. The outlet end of the water spraying pipe 207 is connected to a second spraying ball 208.

[0066] Furthermore, at least one set of grooves 2061 is formed in the first spraying ball 205, and the grooves 2061 are arc-shaped; at least one set of round holes 2081 is formed in the second spraying ball 208.

[0067] In this embodiment, first, through the first spraying ball provided with grooves, the liquid is ejected from the first spraying ball, thereby increasing the spraying area, so that some overly high bubbles are punctured or knocked down. At the same time, for the second spraying ball 208 provided with round holes 2081, the fluid in the water spraying pipe 207 is ejected at a relatively high flow rate, thereby being able to break the bubbles powerfully, and thus improving the working efficiency.

[0068] The usage process and working principle of the present utility model:

[0069] When the present utility model is in use, first, the delivery pipe 201 is connected to an external water delivery device. When it is necessary to remove the bubbles in the tank body 10, the control valve 202 is opened. At this time, the fluid (such as water, etc.) is delivered into the tank through the delivery pipe 201, and the liquid is ejected from the first spraying ball, thereby increasing the spraying area, so that some overly high bubbles are punctured or knocked down. At the same time, for the second spraying ball 208 provided with round holes 2081, the fluid in the water spraying pipe 207 is ejected at a relatively high flow rate, thereby being able to break the bubbles powerfully.

[0070] At the same time, the motor 401 of the driving system 40 is started, and the motor 401 is used to drive the gear transmission 402 to rotate. Then, the gear transmission 402 drives the rotating shaft 502 to rotate. Subsequently, the rotation of the rotating shaft 502 drives the defoamer 501 to rotate, generating a certain centrifugal force. The centrifugal force is used to drive the liquid in the tank body 10 to break the bubbles in the tank body 10.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than restrictive. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that any modification or equivalent replacement of the technical solutions of the present utility model does not depart from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
